"...pushing power in the ether."
According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time. But this ether may not be thought of as endowed with the quality characteristic of matter, as consisting of parts ('particles') which may be tracked through time.
(Albert Einstein, 1928, Leiden Lecture)
The inseparability of time and space emerged in connection with electrodynamics, or the law of propagation of light. With the discovery of the relativity of simultaneity, space and time were merged in a single continuum in a way similar to that in which the three dimensions of space had previously merged into a single continuum. Physical space was thus extended to a four dimensional space which also included the dimension of time. The four dimensional space of the special theory of relativity is just as rigid and absolute as Newton's space. (Albert Einstein, 1954)
That is one complex pen there. Thank you Mr. Einstein, without the Note 4 would Note exist!
